Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of wall-through sealing device of exhaust heat boiler header.
Background technique
Current header sealing to through the wall form, adopts outside to be expansion joint usually, and inner filling rock wool blanket, end steel plate seals.Expansion joint is generally manufactured by professional expansion joint manufactory, increases purchase cost.If rock wool blanket is filled not real-time in expansion joint, then form space, greatly reduce effect of heat insulation; This outer end steel plate and header welding to together with, can only be cut during examine and replace, also must not hinder header cylindrical shell as much as possible, thus add work difficulty.
Model utility content
The utility model is high in order to solve existing header sealing to through the wall cost, and sealing effect is bad, the problem of installation and maintenance inconvenience, and then proposes a kind of wall-through sealing device of exhaust heat boiler header.
The utility model is solve the problems of the technologies described above the technological scheme taked to be: the utility model comprises the first plate-type flange, second plate-type flange, outer sleeve, inner sleeve and flexible graphite stuffing, outer sleeve is sleeved on the outer side wall of header perforate, the bottom of outer sleeve and the outer surface of header affixed, gap is provided with between the outer side wall of outer sleeve and header perforate, flexible graphite stuffing is filled with in gap between the outer side wall of outer sleeve and header perforate, the top of flexible graphite stuffing is provided with inner sleeve, between the outer side wall that inner sleeve is sleeved on header perforate and the madial wall of outer sleeve, the top of inner sleeve is higher than the top of outer sleeve, the top end face of inner sleeve is connected with the first plate-type flange, the top end face of outer sleeve is connected with the second plate-type flange, first plate-type flange is connected by connecting bolt with the second plate-type flange.
The beneficial effect that the utility model compared with prior art comprises is:
1, internal and external casing consumption can be processed with the remaining pipe clout of some stocks seldom completely, and two panels flange adopts plain carbon steel twist drill to hole, and reduces cost.
2, applied widely, not only go for the sealing of header external interface place, header end cap side is suitable for too.
3, is that bolt connects due to what adopt, very convenient for hand hole maintenance, not needing to destroy sealing configuration can overhaul header, is easy for installation and removal, can Reusability, and installation cost reduces more than 80%, and working strength reduces more than 85%.
4, inner stuffing flexible graphite stuffing has applicability extensively, and plasticity is strong, the feature such as high temperature resistant, resistance to strong acid, highly basic, life-span length, selflubricating, low coefficient of friction, and sealing effect is better, and tightness reaches more than 98%.
Accompanying drawing explanation
Fig. 1 is the integrally-built schematic diagram of the utility model; Fig. 2 is the integrated model schematic diagram of the utility model when being applied in header end.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, described in present embodiment, a kind of wall-through sealing device of exhaust heat boiler header comprises the first plate-type flange 1, second plate-type flange 2, outer sleeve 3, inner sleeve 4 and flexible graphite stuffing 5, outer sleeve 3 is sleeved on the outer side wall of header perforate, the bottom of outer sleeve 3 and the outer surface of header affixed, gap is provided with between the outer side wall of outer sleeve 3 and header perforate, flexible graphite stuffing 5 is filled with in gap between the outer side wall of outer sleeve 3 and header perforate, the top of flexible graphite stuffing 5 is provided with inner sleeve 4, inner sleeve 4 is sleeved between the outer side wall of header perforate and the madial wall of outer sleeve 3, the top of inner sleeve 4 is higher than the top of outer sleeve 3, the top end face of inner sleeve 4 is connected with the first plate-type flange 1, the top end face of outer sleeve 3 is connected with the second plate-type flange 2, first plate-type flange 1 is connected by connecting bolt 7 with the second plate-type flange 2.
Waste-heat oven is provided with header, the size of outer sleeve 3 is greater than the size of header perforate, to ensure the flexible graphite stuffing 5 that space is filled with a sealing, outer sleeve 3 is connected with the first plate-type flange 2, second plate-type flange 1 welds with inner sleeve 3, and the first plate-type flange 1 is connected by connecting bolt 7 with the second plate-type flange 2, be combined into a header sealing configuration.The flexibility of the flexible graphite stuffing 5 between outer sleeve 3 and inner sleeve 4 is utilized to realize sealing during use, when external flue gas, waste gas make waste-heat oven inside temperature change, flexible graphite stuffing 5 can expand along with the rising of temperature, extruding header, outer sleeve 3 and inner sleeve 4, thus play the effect of sealing.
